    I forgot to say that I use this llvm build. Just download the release and point the clangd server to it.

    Xtensa support (esp32). Will be interesting how this will be for Rust and Zig support for esp32

    Hopefully, in the future the installation will be simpler, as we are trying to upstream our LLVM changes (first 10 patches are already accepted!), and once we manage to upstream LLVM changes we will proceed with upstreaming our Rust fork changes.

    The main discussion can be led back to this GitHub issue and this comment; fortunately, we don't need to build espressif's llvm fork anymore as they supply the clangd (this is the language server we need) and you can find the zip here. I'll briefly list down the steps required to set up vim with clangd to take advantage of clangd's features (auto-completion, linting, code refactoring ...)

    In my case, it's pretty annoying that the Xtensa platform doesn't have official LLVM support. It's in progress but going very slowly.

    Xtensa. They've got a fork of LLVM that supports it that they're working toward getting upstreamed. The community has a fork of rustc that uses it (and a quickstart crate) while we wait for it to get upstreamed.

    Just to clarify - Gambit, Chicken, and Carp all compile to portable C.

    I hadn't realized LLVM mainline doesn't support Xtensa. I'm surprised.

    D does support Xtensa via LDC (https://forum.dlang.org/thread/[email protected]...). It looks like GDC also nearly supports it, requiring only a minor patch at present.

    A functioning LLVM backend does exist (https://github.com/espressif/llvm-project/issues/4) and might be making very slow progress towards being merged. A quick search shows that it works for Rust. I suspect (but don't know) that it might work for Terra as well.

    There's also the LLVM C backend (https://github.com/JuliaComputingOSS/llvm-cbe) but I've no idea how efficient such an approach is when applied to real world embedded tasks.
